AI Technical Summary
Technical Problem
In the case of a faulty C-contact relay, the existing charging and discharging system may cause mismatched power to be applied at the device interface, posing a safety hazard.
Method used
A bidirectional charging and discharging system is adopted. The voltage at the inlet and outlet is detected by the first and second voltage sensors. When the control device detects AC voltage at both the inlet and outlet, it determines that the switching system is faulty, prohibits charging and discharging, and prevents the application of power.
Benefits of technology
This effectively reduces the application of unsuitable power at equipment interfaces, improves system safety and reliability, and prevents equipment damage.

Abstract
本发明涉及充放电系统、车辆以及充放电系统的控制方法。充放电系统能够在与外部之间进行充放电，具备放电电路、切换系统以及控制装置。充放电电路除了将来自接入口的电力转换为适合于蓄电装置的直流电力之外，还将蓄电装置的直流电力转换为从接出口放出的电力。切换系统将充放电电路与接入口或者接出口连接。控制装置以在接入口检测到交流的电压并且在接出口检测到交流的电压为条件，判定为切换系统发生故障，进行控制以禁止充放电。
